To all whom it may concern:

Be itknown that I, HENRY M. GL-EASON,

a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new "'and useful Mechanism for O erating Water-TightBulkhead-Doors, of which the following is a specification.

My invention relates to improvements in mechanism for operating watertight bulkhead doors on ships.

The object of my invention is to provide means for operating waterti ht bulkhead doors that is entirely indepencent of power generated by a pliances aboard ship, thus licated and ex ensive mechanisms with their attendant isadvantages.

I- accomplish my object by providing a watertight door, which may be 0 ened or closed through suitable mechanism by the: pressure of the head of water in which the ship is floating. The location of waterti ht doors, which are required to be operated y power, is some distance below the level of the water in which the ship is floating, and the pressure of the head of water at this location is a source of power. This power, I utilize, by suitable means, to o crate the watertight door at the door itse f, and I also provide means for. controlling from a distance, said operating means.

Various systems for operating watertight doors have been employed, using pneumatic, hydraulic, or electric power, but 1n all these systems the necessary ower has been generatedby appliances in t e ship.

Referring to the drawin s:1 igure 1 is a front elevation of the bulk ead door and its 0 crating mechanism; the cylinders being s own in section. Fig. 2 is a top plan view. Fig. 3 is a section on line 3, 3 of Fig. 1.

1 i. 41s a cross-sectional view of the ships hulfi with my im roved mechanism showndlagrammatical y.

Similar numerals refer to similar parts throughout the several views.

The movable member or door 4 is of the horizontal sliding t e, and is provided with the frame 5, an t e usual wedges, fittings, etc.

The cylinder 6 contains the piston 7, fixed to the piston rod 8, which is secured to the 9, and the pin 10. From the cylinder 6 the pass es 11 and 12 are arranged as shown, so that 'y the movee slide valve 13 in one direction the passage 11 will communicate with chamber-14, and the passage 12 with chamber 15, and vice versa when the slide valve is movedin the opposite direction. Chamber 14 is in communication withwater from the outside of the ship by means of the pipe 16 which is connectedto the sea chest 43 controlled by valve 44 nearest the door. Chamber 15 is in communication with the bilgcs ol' the ship by means of the drain pipe 17. The chamber 14 is in communication with the chamber 18 by means of the small passage 19 which serves to equalize the )IGSSUIG 01'' water on both sides of the small piston 21).

Fromchamber 18 a drain pipe 21 cominunicates with the bilges when either the automatic valve 22, or the emergency valve 23 is open. The small piston rod 24 on which is secured the piston 20, is attached to the slide valve 13, so that the movement of the slide valve corres onds to that of the small piston. The small piston rod 24 is operated in either direction by the hand lever 25. The slide valve 13 is held in place against the valve seat by the spring 26, the roller 27 being provided to decrease friction. The set screw 28 is provided for adjusting the effort of the spring 26 when necessary.

Communicating with the drain pipe 21 is the pipe 20, in which is fitted the automatic valve 22. The automatic valve is kc )1, closed by the action of the weight of the float 30 about the pivot 31. The valve rod 32 is secured to the lever 33. When water rises in thecompartment the float in rising causes the valve to be opened. There is also communicatin with drain pi )e 21, the emergency va ve 23, from which leads the pipe 34 to the bilges. The valve 23 may be 0 erated by the valve rod 35 and hand w eel 46 from the emergency station usually in pilot house 41 on the bridge 45. When the door is entirely closed an electric contact maker 36 of the usual type is operated and the closing of the door indicated at the emergency station by the lighting ofan incandescent lamp 42. The wires connecting the contact maker with the lamp are carried in the conduit 37, see Figs. l and 4.

The 0 eration of the mechanism is as follows ith the door open as shown in Fig. 1,

and the valves 22 and 23 in their usual conwater from the sea to enter the left end of the c linder and exhaust from the right end into t e drain pipe 17 to the bilges. The pressure of the water moves the piston and closes the door. To open the door the operation is reversed. The off position of the valve is shown in the drawing, Fig. 1.

In Fig. 2 is shown a second hand-lever 4O operatively connected with lever 25 by s raft 39. This lever 40 is on the other side of the'bulkhead from lever 25, so that valve 13 may be operated by hand from either side of the bulkhead.

To close the door from the emergency station, the valve 23 is opened by the valve rod 35. This allows water in the chamber 18 to escape and the pressure on that side of the snia 1 piston 20 is likewise released. The pressure of water in the chamber 14 acting on the other side of the small piston operates the slide valve in such a manner that the pressure of water in chamber 14 is communicated to the left end of the piston 7 and the dooris closed. If while the door is thus closed by the emergency action, it is necessary to open it for any cause at the door itself, this may be done by operating the hand lever 25. In so doing the pressure of water in chamber 14 against thesmall piston must be overcome. When the hand lever is released the pressure of water against the small piston immediately operates the slide valve to close the door again.

The door is closed automatically, when water gains admittance to the compartment, by the action of the float 30 which rises and actuates the valve rod 32. This opens the valve 22 and allows the water in pipe 21, and consequently chamber 18, to drain into the bilges through the pipe 38. The release of water from chamber 18 causes the pressure of water in chamber 14 to operate the small piston 20, as described above in case of the emergency station.

The system above described for one door may be extended to include any desired number of doors.

The door shown in the drawing is of the horizontal sliding type, but my device is also adapted to be employed for operating watertight doors, diflerently supported or moving in diflerent directions.
